Notes: Data cover only CO 2 capture <strong>and</strong> compression but not transportation <strong>and</strong> storage. Overnight<br />
costs include owner’s, EPC <strong>and</strong> contingency costs, but not IDC. A 15% contingency based on EPC cost<br />
is added for unforeseen technical or regulatory difficulties for CCS cases, compared to a 5%<br />
contingency applied for non‐CCS cases. IDC is included in LCOE calculations. Fuel price<br />
assumptions differ between regions.<br />
Oxy‐combustion CO 2 capture <strong>from</strong> coal‐fired power generation<br />
<strong>Cost</strong> <strong>and</strong> performance data for oxy‐combustion CO 2 capture <strong>from</strong> coal‐fired power generation<br />
are shown in Table 7. Techno‐economic data for 11 different cases <strong>from</strong> 5 organisations are<br />
analysed, including a case study for an installation in China. It should be noted a particularly large<br />
number <strong>of</strong> data stem <strong>from</strong> a single recent US Department <strong>of</strong> <strong>Energy</strong> assessment (NETL, 2010e).<br />
Oxy‐combustion capture <strong>from</strong> SCPC <strong>and</strong> USCPC boilers that operate on bituminous coals are<br />
most <strong>of</strong>ten evaluated in the reviewed studies. Additional data cover CFB boilers, <strong>and</strong> plants<br />
operating on sub‐bituminous coals or lignite.<br />
Average published capacity factors are 85% for the cases shown; CO 2 capture rates are 92%. Net<br />
power outputs including CO 2 capture range <strong>from</strong> 500 MW to 550 MW in <strong>OECD</strong> countries, at an<br />
average net efficiency <strong>of</strong> 31.9% (LHV).
